Narita International Airport
The international airport and gateway to Tokyo, visited by 44 million travelers each year (as of 2019). Opened in 1978, this world-famous airport (airport code NRT) has ferried over 6 million flights both in and out of Japan. The airport grounds include 3 different passenger terminals, a freight terminal and is currently planning to open a new runaway in addition to its two runways currently open.
Since they changed the shuttle bus system at the terminal, you have to walk a bit farther now, but the whole place feels much more open and pleasant.
